Extension center educators, unit educators, and unit assistants in northern, west-central, east-central, and southern Illinois prepare regional reports to provide more localized insight into pest situations and crop conditions in Illinois. The reports will keep you up to date on situations in field and forage crops as they develop throughout the season. The regions have been defined broadly to include the agricultural statistics districts as designated by the Illinois Agricultural Statistics Service, with slight modifications:|
· North (Northwest and Northeast districts, plus Stark and Marshall counties)
· West central (West and West Southwest districts, and Peoria, Woodford, Tazewell, Mason, Menard, and Logan counties from the Central district)
· East central (East and East Southeast districts [except Marion, Clay, Richland, and Lawrence counties], McLean, DeWitt, and Macon counties from the Central district)
· South (Southwest and Southeast districts, and Marion, Clay, Richland, and Lawrence counties from the East Southeast district)
We hope these reports will provide additional benefits for staying current as the season progresses.
Several scattered thunderstorms during the past week brought needed rainfall to the region. However, recorded precipitation ranged from less than 1/2 inch to more than 3 inches. Corn yields have been adversely affected in many areas last week due to the dry soil conditions coupled with high temperatures.
Concerning insect outbreaks, some soybean field borders have been treated for spider mite infestations. Also, as always, alfalfa growers are encouraged to scout for potato leafhoppers, as populations remain high throughout the region. Japanese beetles have been observed frequently in soybeans and noncrop areas, but few instances of silk clipping have been reported.
There is consensus that it is hot in southern Illinois. We are losing some yield from high daytime and nighttime temperatures. Moisture continues to be quite variable across the region. Spotty rain showers have favored one location and skipped others.
Corn is R3R4, with some close to beginning dent. Soybeans are R3R4. Double-cropped soybeans have made good progress also.
There are no serious pest problems at present. Southwestern corn borer moth flight is still high, especially in the southern counties. Waterhemp keeps on coming.
Remember the Dixon Springs Ag Center Field Day, August 2. Tours start at 8 a.m.
Rain and warm temperatures continued during the week in most of the region. Some areas will end July with above-normal precipitation for the month.
As a result of the recent rain, crop conditions look very good. No major pest problems have been reported in corn. However, if warm and humid conditions persist, some leaf diseases may appear. Rapid crop development continues, and many farmers anticipate an early harvest.
Soybean growth has been rapid during the last week; plants grew noticeably taller. Spider mite problems subsided when the rains began. Some bean leaf beetle feeding has been observed. No other problems have been reported.
Potato leafhoppers continue to be a major pest problem in alfalfa.
Major activities for area farmers now include mowing and attending field day meetings and county fairs.
